enricobuehler	8ab262f8f8	feat(trust): host-gated trust-on-first-use — PIN pairing mandatory by default ... TOFU let anyone who could reach the host click "Trust" and stream, which defeats the point on a LAN. Make SPAKE2 PIN pairing the default and only way to trust a NEW host; TOFU survives as an explicit HOST opt-in (for fully trusted networks), advertised over mDNS so clients render their trust UI from the host's policy rather than offering trust on faith. Contract: - Host advertises pair=required (default) or pair=optional. pair=required rejects unpaired clients at the handshake; pair=optional accepts them (TOFU). - Clients: a pinned host whose fingerprint matches connects silently; a pinned host whose fingerprint CHANGED forces re-pairing via PIN (no re-trust shortcut); a NEW host is offered TOFU only if it advertised pair=optional, otherwise PIN pairing is mandatory; a manually-typed or unknown-policy host is always PIN. Host (crates/punktfunk-host/src/main.rs): - m3-host now REQUIRES pairing by default (was open by default). New --allow-tofu opts into accepting unpaired clients + advertising pair=optional; pairing is always armed (PIN logged at startup). serve --native was already secure-by-default (serve --open). The mDNS advert and the accept loop already mapped require_pairing -> pair=required + reject; only the m3-host CLI default + help text changed. Clients honor the advertised policy: - Android (MainActivity.kt): TOFU only for a discovered pair=optional host; manual/unknown -> PIN; fp-change -> re-pair only (dropped the "Forget & re-TOFU" shortcut). - Apple (HostDiscovery/SessionModel/ContentView/HostCards/HostStore): new allowsTofu (pair==optional, distinct from unknown); connect() gates .awaitingTrust on it; unpinned non-optional hosts route to the PIN sheet; "Forget Identity" re-pairs rather than re-TOFUs. - Linux (app.rs/ui_hosts.rs/session.rs): ConnectRequest.pair_required -> pair_optional; initiate_connect routes pinned/fp-changed/optional/else; manual + --connect unknown -> PIN; a pinned connect rejected on trust grounds re-pairs. Docs (CLAUDE.md, README.md, docs-site/content/docs/pairing.md): describe the gated model — PIN is the default, TOFU an explicit opt-in with an impostor warning. Verified: host cargo check/clippy/fmt clean; Android built + live (emulator -> home-worker-2): a manual connect now opens the PIN dialog (no Trust button) and the PIN ceremony streams; Apple swift build clean; Linux clippy -D warnings + fmt clean on the Linux box.

enricobuehler	6d3ff37d9e	feat(client): cross-target input handling + LAN mDNS discovery ... Input handling, building on macOS/iOS/tvOS: - macOS recapture after navigating out: engageCapture no longer latches captured=true when the cursor grab is refused mid app-activation (which left a free cursor that no later click could re-grab); cursorCapture.capture() now reports success. + canBecomeKeyView. - iOS/iPadOS recapture: restore the prior capture on didBecomeActive (nothing re-grabbed mouse/keyboard on return before). - iPad indirect pointer (no lock) is forwarded as an absolute MOUSE (move + buttons + scroll via hover / UITouch.indirectPointer), not as touch, with the local cursor visible; GCMouse owns the locked regime, gated so the two never double-send. Adds the MouseMoveAbs wire helper. - Trackpad scroll on iOS (was entirely missing): GCMouse scroll dpad when locked + a scroll-only UIPanGestureRecognizer otherwise. - tvOS: no focusable control during play (a focusable Disconnect button ate the controller's A in the focus engine); Siri Remote Menu disconnects. - Don't leak touch to the host under the TOFU trust prompt (gate on captureEnabled). LAN discovery: HostDiscovery (NWBrowser over _punktfunk._udp, the host's crate::discovery advert) resolves each service to IP:port and parses the TXT (fp advisory, pair, id); an "On this network" section in the grid (tap to save + connect, or pair if required). iOS/tvOS get NSBonjourServices via a merged Config/Info.plist. Integration-tested end to end against a fake NWListener advert. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>	2026-06-12 14:08:19 +02:00
